in stile grooves. n

It is an object of the invention, among other things, to provide a window wherein the sash is pivotally mounted on its slides and is adapted to be movedabout a horizontal I '110 axis, and swung inwards to a slight extent for purposes of ventilation at any vertical position ofthe slides in their stile grooves.

Another object of the invention is to provide a window wherein the sash is adapted to ,15 be'swung inwards into a substantially horizontal position when it and its slides have been raised to a predetermined position, and wherein means are provided for locking the slides against vertical movement in their stile stantially vertical position. Y

With these and other objects and advantages in view,`which will become apparent as the specification proceeds, an embodiment of the invention is hereinafter more fully described with the aid of the accompanying drawings, in which: f

Figure 1 illustrates a side elevation looking onto a plate pivotally mounted on one slide to which plate one side of a sash is adapted to be secured; the position of the sash when in partly open position is also indicated.

Figure 2 is a front elevation of part of a sash showing parts of the frame and corelated portions in section. f

Figures 3 and 4 are enlarged sections on the lines 3 3 and 4 4 respectively.

Figure 5 is an enlarged detail.

Figure 6 shows a side view, partly in secl tion, of a sash plate in its substantially horizontal position and the corelated parts.

Figure 7 vis an enlarged detail of the slide, and catch in the stile groove.

Figure 8 is a section on the line 8-3 of Figure 7 and is continued downwards to illustrate the pivotal mounting of the sash and sash plate.

Figure 9 is an enlarged sectional lview of the dog retracting mechanism, and

Figure 10 depicts an enlarged view of the` engaging member.

Referring to the drawings, 1 designates a window having stile grooves 2 in which slides 3 are adapted to move vertically. The slides consist of substantially channel shaped members having their` open sides outwardly disposed, and inwardly directed flanges 4 along their rear margins forming receiving grooves 5 open from the front. Lengthwise of the sides of a sash 6 sash plates 7 are secured. The rear margins 8 of the plates 7 are spaced from the sides of the sash and are adapted to engage the ygrooves 5 thereby functioning as weather stripping; and intermediately of the length of one of these sash plates a portion of its rear margin is cut away so that'that portion of that plate, when parallel with its slide7 terminates flush with the front edge of the adjacent flange 4.

The inner side of one of the sash plates 7 is provided with a longitudinal groove 9 to receive a portion of a sliding member 10 to which an extension arm 11 is pivotally attached. The opposite end of this extension arm is pivotally fastened to one end of an arm 12, and the opposite end of the latter is pivotally attached to the slide 3. The arm 12 and its extension 11 are so positioned that when the sash is in vertical position they lie in one of the receiving grooves 5 and opposite the sash plate portion 7 the rear margin of which is cut away. Hinge pins 13 extend through the lower ends of the slides 3, sash Vplates 7, and take into the sides of the sash 6. These pins13 may be held in position as by springs 111.

Pivotally mounted within the channelshaped portion of one of the slides 3 is an arm 15 normally held forwardly by a spring 16 through this arm is a locking pin 17 which projects through a slot 18 in the slide 3 and is adapted to be engaged by a recess 19 in the rear edge of one of the plates 7 when the sash is in vertical position. On the central face of one of the stile grooves 2 is a 'catch 20 having a receiving slot 21 therein. When the sash is swung inwardly so that the pin 17 is released form the recess 19 and may be moved forwardly by the spring 16 the pin engages the slot 21 provided the sash and its slides have been raised to such a height that the pin and slotcome into engagement. When this occurs the sash and slides are held against vertical movement in their stile grooves. Other means ii'or holding the sash and slides against veitical movement when the former is moved pivotally may be employed when desired.

Secured to the outer side of one of the slides 3 is a flat spring 22 having an opening 23 therethrough towards its free end, and opposite the opening 23 an aperture 24 is provided through the central portion of the slide. A dog 25 passes through the opening l23 in the spring 22 and is so held thereby that its inner end normally projects through the slide aperture 24. On the outer end of the dog 25 is a transverse portion 26 which is spaced outwardly from the said spring 22. On the central face of one of the stile grooves 2 an engaging member 27 is arranged which is adapted to engage the inner sides oi the transverse portion 26 of the dog 25 and draw the latter outwardly as the sash is moved vertically in its stile grooves so that at one position of the slides and sash 'the dog is brought outwardly substantially flush with the inner side of its slide. Incidentally this should occur when the locking pin 1'? is opposite its slot 21, so that the slides and sash are locked against vertical movement at the time the dog is wthdrawn; for obviously when the latter occurs the arm 12 is lfree to swing into the position shown in Figure 6. 28 denotes a conventional type of fastener for holding the upper sides of the sash in engagement with the slides.

From the foregoing it will be seen that. at any vertical position of the slides and sash the latter may be moved pivotally to the limit of movement permitted by the arm extension 11, as indicated in Figure 1. When the slides and sash have, however, been raised to such position that the engaging member 2T retracts the dog` 25, the arm 12 is then also free to swing so that the sash may be brought into a substantially horizontal position as indicated in Figure 6.

While in the above description the preferred construction has been described, it is understood that the invention is subject to such alterations and modiiications as fall within the scope of the appended claims.

lVhat I claim as my invention and desire to secure by Letters Patent is:
